Old towel and scissors was all I needed. Didn't use velcro or sew ends, I just used some rubber bands and attached the "arms" and "legs" of the H around the Swiffer.
Pinner says this works! I did it on all my outside windows and now they look amazing!
stick decals onto canvases, paint the whole thing and then remove the stickers to reveal the wonderful artwork! (literally so simple anyone could do it & it looks amazing!!)
